ATTACHMENT FOB. WINDOWSHADES.

Application filed June 21, 1916.

To all whom it may concern.-

Be it known that I, EMIL WINTERER, a citizen of the United States,residing at Manchester, in the county of Hillsboro and State of NewHampshire, have invented certain new and useful Improvements inAttachments for VVindow-Shades, of which the following is aspecification.

This invention relates to attachments for window shades, and moreparticularly to an attachment for a window shade to prevent overwindingof the same.

One of the main objects of the invention is to provide an attachment ofthe characterstated of simple construction and operation. A furtherobject is to provide an attachment which can be manufactured in largenumbers at very small cost. Further objects will appear from thefollowing detailed description.

In the drawings:-

Figure l is a side view of the invention as applied,

Fig. 2 is a perspective view of the attachment, and

Fig. 3 is a modified form of the invention.

The curtain pole 1 is mounted in brackets 2 secured to the window casing3, in the usual manner, and carries a shade l of any suitableconstruction. This shade is turned back upon itself, at its lower end,to receive the usual rod or stick 5.

To this stick, at the longitudinal center thereof, I secure my brakingattachment designated by 6. This device is formed with a book 7 which isadapted to fit tightly about the stick 5, and is provided with anaperture 7 at its lower end to receive the usual screw eye 8 which isthreaded into the stick 5, the pull cord 9 carrying the ring 10 beingsecured through the eye 8, as is usual. The body 11 of the brakingdevice is curved upwardly and backwardly, the outer end being coiledupon itself to form a tube 12. 11 I provide a cushion stud 13 of rubberor other suitable resilient material. The hook 7 and body 11 are formedintegral, as shown, the whole device being made from sheet spring steel,or the like, so as to be durable and have a great deal of resiliency.

If, in winding up the shade, the pull cord 9 is accidentally released ata point where the dogs which are provided on roller 1 Specification ofLetters Patent.

and act in the usual manner, have not locked the roller againstrotation, the shade will fly upward due to the sudden release of theroller. This results in overwinding of the shade causing the cord towrap around the shade and roller and thus become entangled with thesame. This is a well known fault with shades of the ordinary type and isoften experienced when the shade is ac cidentally released as abovedescribed. With my attachment secured on the shade, if the shade bereleased in this manner, the cushion stud 13 will engage the under faceof the top board 3 of the window casing thus preventing overwinding ofthe shade. Due to the resiliency of the stud 13 and the member 6, damageto the shade from stopping it too suddenly is effectually avoided.

In Fig. 3, instead of securing the device 6 to the shade stick 5 bymeans of the screw eye 8, I provide it with a spring clamp let in placeof the hook '7. This clamp is adapted to fit tightly about the stick 5and thus secure the attachment thereto.

By having the upper outer end of the device of tubular shape all dangerof its engaging curtains, which may be hung inside of the shade, isavoided, as there are no sharp projections to engage in curtains or thelike. The outward curvature of the body 11 of the attachment will dependlargely upon the type of shade with which it is used, it being such asto bring the cushion stud 18 in proper position to engage the under surface of the top board 3 of the window casing 3, as above described. As alarge majority of shades and brackets are of standard construction, mydevice can be made of a particular standard size and shape, but may bevaried to suit special sizes.

In addition to exerting a braking effect upon the shade if accidentallyreleased, my device is also adapted to prevent rattling of the shade inthe event of the window being opened at the top and the shade being in araised position, such as it occupies in Fig. 1. In this case, thecushion stud 13 is in frictional engagement with the top board 3 of thewindow casing and efl'ectually prevents free swinging in and out of thecurtain under the influence of the incoming air current, thus preventingany rattling such as would occur if the shade were perfectly free.
